Why not just wait until "the Church settles this matter in a saner day", and in the meantime do as St. Vincent of Lerins says: "Cleave unto antiquity" and go back to the 1954 Missal?
Because not all changes/updates to the missal are wrong; some are very necessary - like adding saints to the calendar or simplifying the feast day hierarchies (both of which the 1962 missal did, as Fr Wathen pointed out).
Pope St Pius X completely overhauled the Breviary 100 years ago? I mean, the changes he made were DRASTIC. The breviary/Divine Office today is NOTHING like it was before his changes. Can we say that Pope St Pius X's changes were anti-Tradition or that what he did was anti-antiquity? Of course not.
Further, what about the 1954 missal? What missal came before it? Why is the 1954 missal allowed to have changes/updates but the 1962 missal cannot? What are you comparing the changes against, to make your determination of what is acceptable or not?
The only way to have a "litmus test" on missal changes, is 1) to realize that a pope has the power over the liturgy, in all non-essential, non-Divine origin matters and 2) if the prayers/rubrics are of human/Church origin (and not Apostolic/Divine origin) then the Church/pope can change these.
